Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset estimates the level of connectivity between each area containing coral reefs and other such areas. Connectivity refers to the extent to which populations are linked by the exchange of eggs, larval recruits, juveniles, or adults—an exchange which is primarily conducted via ocean currents. A coral larvae dispersal probability model developed by Wood et al. was applied by the 50 Reefs Project to simulate coral exchange between 2003 and 2011, ultimately yielding connectivity estimates globally at 0.05° resolution. These estimates were based on potential dispersal only; settlement and post-settlement survival were not modelled.</SPAN></P><P><SPAN /></P><P><SPAN>Connectivity within and between protected areas is important for maintaining diversity, fish stocks, and especially important for maintaining ecological resilience. While poorly understood, it is a key factor to consider in marine reserve design as it may enhance resilience to disturbance and be important for the persistence of populations. Both of these are important processes in the context of conservation planning under climate change, the dominant threat to coral reefs in the coming decades. Even if the goals of the Paris Climate Agreement are achieved, 70-90% of coral reef areas are likely to cease to be suitable for coral growth by mid-century. Coral communities that survive will play a key role in the regeneration of reefs by mid-to-late century.</SPAN></P><P><SPAN /></P><P><SPAN>The purpose of the 50 Reefs Project was to develop a long-term strategic plan for the conservation of coral reefs by identifying 50 large (500 km²) regions that are the least vulnerable to climate change and which are positioned to facilitate natural coral reef regeneration. These locations constitute important opportunities for novel conservation investments to secure less vulnerable yet well-connected coral reefs that may help to repopulate degraded areas after the climate has stabilized. The strategy and actions proposed by the project should strengthen and expand existing conservation efforts for coral reefs as the world faces the long-term consequences of intensifying climate change.</SPAN></P></DIV></DIV></DIV>
